Answer:
when x = 5, the value of the expression 5x^2 - 2x + 5 is 125.
Explanation:
To find the value of the expression 5x^2 - 2x + 5 when x = 5, we simply substitute 5 for x and evaluate:
5x^2 - 2x + 5
= 5(5)^2 - 2(5) + 5 (substituting x = 5)
= 5(25) - 10 + 5
= 125 - 10 + 5
= 120 + 5
= 125
Therefore, when x = 5, the value of the expression 5x^2 - 2x + 5 is 125.
